我使用MPMoviePlayerViewController在iPhone4(iOS5.1)，新iPad(iOS5.1)，iPad(iOS4.2)的iOS应用中播放视频.

I use MPMoviePlayerViewController to playback videos in my iOS app on iPhone4 (iOS5.1), new iPad (iOS5.1), iPad (iOS4.2).

播放视频时，我按了两次主屏幕按钮，显示了多任务底座，播放器暂停了.

I press home button twice when playing a video, the multitask dock shows and player pauses.

我试图在appDelegate applicationWillResignActive中调用播放器的play方法，但是没有用.

I have tried to call player's play method in appDelegate applicationWillResignActive,but it didn't work.

有人知道如何避免玩家停顿吗?

Does anyone know how to do to avoid player pause ?

另一个问题，如何在遥控面板上显示视频的标题? (将多任务扩展坞滑动到最左侧).

Another question, how to show video's title on remote control panel? (swipe multitask dock to leftmost).

谢谢.

推荐答案

我认为您不应该继续播放视频.根据《 Apple App编程指南》，您应该在发生这种情况时暂停应用程序中的视觉活动.我不能100％确定App Store提交的内容是否会接受该行为.

I don't think you shouldn't continue playing the video. According to Apple App Programming Guide, you are supposed to pause visual activity in the application when that happens. I am not 100% sure if the App Store submission will accept that behavior.

您可以通过向MPNowPlayingInfoCenter提供元数据来显示视频标题:

You can show the video title by providing metadata to the MPNowPlayingInfoCenter:

如此处所写:

系统在设备锁定屏幕和多任务UI的多媒体控件中显示正在播放的信息.

The system displays now-playing information on the device lock screen and in the multimedia controls in the multitasking UI.
